Disney is rushing emergency supplies of Frozen merchandise to the UK after costumes, dolls and soft toys ran out.
The blockbuster animated musical has proved a huge hit with parents clamouring to snap up costumes like Elsa's shimmering blue dress or Anna's caped outfit and plaited wig for their children.
But demand became so high that Disney started selling out and even had to impose quotas on some of the merchandise to create an 'equitable way' to buy the most popular stuffed animals and dolls.
Shoppers on the Disney website can put only one of the £15 Elsa and Anna dolls in their basket and in the US some stores have even been running lotteries to buy the products.
Disney admitted that the industry had underestimated Frozen's success. Now, Disney says relief is on the way.
A Disney UK spokesman told The Observer: "The popularity of Frozen has been phenomenal. "We are thrilled that audiences have connected with the characters and story in the way that they have and we are working hard to keep bringing additional product into stores as quickly as possible."
Frozen, based on Hans Christian Andersen's fairy tale The Snow Queen, is officially a blockbuster franchise after it overtook Toy Story 3 in March to become the highest grossing animated film of all time, raking in £644 million at the box office.
It was in the UK box office top 10 for more than three months and now ranks as the 10th highest grossing film in cinema history.
Despite a lukewarm critical response, the film won two Oscars, and its songs topped the US Billboard 200 chart for 13 consecutive weeks. A Broadway musical is also now in development.
